摘要: 以茄子和朱砂叶螨为对象,对叶螨种群动态与植物次生代谢物质——丹宁酸含量变动的相互关系进行了研究.发现朱砂叶螨的取食胁迫,能迅速地诱导茄子的应激反应.同时茄子以某种方式的丹宁酸含量自主调控,对叶螨种群的动态产生强烈的影响.在结合考察未受螨害植株所表现出的次生代谢准周期变动的基础上,提出了一种植物防御模式的假说.

Abstract: Under infestation of Tetranychus cinnabarinus, Solanum melongena can initially regulate its relative level of secondary metabolism, inducing the synthesis of anti-insect secondary metabolite-tannic acid to restrict the increase of red spider population. Meanwhile, a secondary metabolism with a semi-cycle of two to three weeks is found in normal plant. The cause of this cycle and its effect on pest population are analyzed and discussed.
